DSTV, account not adjusted as advised resulting in incorrect (increased) debit.

Earlier this month, I complained about being incorrectly debited. I was contacted by Multichoice and was informed that the running total will be adjusted to the correct amount of R799, around the 20 November. I followed up and I I noted that it was not adjusted. I did reply to Multichoice's feedback on my initial complaint advising this. Yesterday (25 November), I got debited for R1047.15. I called Multichoice and had to explain the whole incident again. I was put on hold for abt 5 to 6 minutes when my airtime ran out. Please can someone resolve this matter urgently. Its such a mission to call multichoice and have to speak to a different person each time.
